If you aren't familiar with Hip Hop Family Tree Comics, start with this week's Boing Boing installment, then gorge on archives or buy a copy. Ed Piskor's comic has become something I greatly anticipate every week.

Everyone knows arsenic is a poison, but did you know it's in your water too? Low levels of arsenic in your glass are naturally occurring. The Environmental Protection Agency says that drinking water must have fewer than 10 parts per billion of arsenic to prevent harmful effects of long-term exposure. According to the 2010 report by the Albuquerque Bernalillo Water Utility Authority, these water zones have as high as 8 parts of arsenic per billion. It’s worth keeping an eye on.

The EPA says the Sandia Labs Mixed Waste Landfill isn’t a threat, but a 2011 report by Citizen Action says otherwise. The mixed-waste landfill lies directly above the main source of water for 600,000 Albuquerque residents. From 1959 to 1988 the landfill was used for disposal of low-level radioactive materials. Contaminants include nickel, cadmium, nitrate and chromium, all of which can cause nasty health problems with overexposure. What’s more, Mesa del Sol—a “green” community development touting that its “respect for the environment result[s] in a healthier, simpler, more sustainable way to live”—just broke ground adjacent to the site.
